Aim. To investigate the life expectancy and reproductive activity of Drosophila melanogaster that developed in conditions of increased larval density. Methods. Mean and maximum life span were determined in males and females in the different experimental groups. The reproductive activity was evaluated by counting the total number of eggs laid by one female per day. Results. A significant increase of the mean life span compared to control was observed in adults that hatched from pupae during the first and second days after the beginning of the emergence: males — 24 % and 23.5 %, females — 23.8 % and 29.3 % respectively. The level of reproductive activity (fecundity) is statistically lower in two groups which hatched last. Conclusions. Based on the results obtained, we suggest that development in conditions of increased larval density can lead to increase in the life span of D. melanogaster.Keywords: life span, Drosophila melanogaster, reproductive activity, development.
